If you’re looking for a way to gauge how the 3D printing market will evolve, look no further than the dawn of two other revolutionizing technologies – the desktop printing market and the VHS standard. And be prepared for a decidedly off-color story. While many of us have fond memories of watching a favorite movie when it first came out on VHS, or admiring the first three-color party invitation we printed on a laser printer, the fact remains that innocent pursuits were not the sole reason either of these technologies took off. While it’s clear that most applications of these technologies were G-rated, there were plenty that weren’t. And when it comes to 3D printing, that unwholesome and downright illegal activity called counterfeiting is likely to become one of the major reasons why 3D printing will be a major growth industry in the coming years. And 3D printing will have its fair share: from the manufacture of prosthetics and spare parts to on-demand organs, foods, and your child’s next toy, the 3D printing revolution will by and large have a positive impact on society as a whole.
